progressreader.Broadcaster becomes broadcaster.Buffered and
broadcastwriter.Writer becomes broadcaster.Unbuffered.
The package broadcastwriter is thus renamed to broadcaster.

- Rename to Broadcaster
- Document exported types
- Change Wait function to just wait. Writing a message to the writer and
adding the writer to the observers list are now handled by separate
function calls.
- Avoid importing logrus (the condition where it was used should never
happen, anyway).
- Make writes non-blocking

Previously, its other return value was used even when it returned an
error. This is awkward and goes against the convention. It also could
have resulted in a nil pointer dereference when an error was returned
because of an unknown pool type. This changes the unknown pool type
error to a panic (since the pool types are hardcoded at call sites and
must always be "push" or "pull"), and returns a "found" boolean instead
of an error.

Based on #12874 from Sam Abed <sam.abed@gmail.com>. His original commit
was brought up to date by manually porting the changes in pull.go into
the new code in pull_v1.go and pull_v2.go.

package, and generally cleanup and simplify the codebase.
